I got the unit apart today and found that the seals in the kit do not match the ones I took out except for the "8" looking seal. In the second picture, the original seal is the one on the bottom. In the third picture, the original seal is the bottom right. I believe this unit has been worked on before. The charged cylinder has the QR code sticker. It comes back to a Cardone 52-7307.
Now to figure out how the get the same seals. I bought the 501 seal kt.
